To verify the influence of age on factors associated with peri-implant bone loss after prosthetic rehabilitation over osseointegrated implants.
This is an analytical, observational, and longitudinal study with initial 23 participants. Patients presenting with osseointegrated implants with their respective prostheses installed were included, and they could be carriers of chronic and degenerative diseases, such as diabetes, osteoporosis, hypothyroidism, cardiovascular disease (CVD), and systemic arterial hypertension. Thus, 18 participants with 57 implants were selected and followed up from 2009 to 2013. For statistical analysis, chi-square or Fisher's exact test was used for the association of systemic conditions and bone loss. Student's t-test was used for mean comparisons of age and number of total upper and lower implants.
The average age of the sample studied was 71.05 years (65-80). The average implant per person was 3.2. Smoking had an influence on both mesial and distal bone loss, and the latter was significant (p = 0.0370). The association between bone loss and gender was also significant (p < 0.05). Moreover, male gender and upper implants were factors significantly associated with bone loss. The systemic conditions, when isolated, did not have significant influence on implant survival.
Age is not a factor that, alone, contraindicates implant-rehabilitating therapy. On the contrary, smoking has a significant influence on dental implant survival. Systemic diseases, such as osteoporosis, hypothyroidism, diabetes, hypertension, and heart diseases, when controlled, are not contraindication factors.
This study is relevant for assessing peri-implant bone loss in elderly patients, right after implant installation and over time. Therefore, it was possible to verify that age is not a limiting factor for this procedure. Controlled systemic diseases do not contraindicate implant installation, but smoking is a factor that affects implant survival.
验证年龄对骨结合种植体修复后种植体周围骨丢失相关因素的影响。
这是一项分析性、观察性纵向研究，最初有23名参与者。纳入已安装各自修复体的骨结合种植体患者，他们可能患有慢性和退行性疾病，如糖尿病、骨质疏松症、甲状腺功能减退症、心血管疾病（CVD）和系统性动脉高血压。因此，选取了18名参与者的57颗种植体，并在2009年至2013年期间进行随访。对于统计分析，采用卡方检验或Fisher精确检验分析全身状况与骨丢失的相关性。采用学生t检验比较年龄以及上下颌种植体总数的均值。
所研究样本的平均年龄为71.05岁（65 - 80岁）。人均种植体数量为3.2颗。吸烟对近中及远中骨丢失均有影响，且远中骨丢失具有显著性（p = 0.0370）。骨丢失与性别之间的关联也具有显著性（p < 0.05）。此外，男性和上颌种植体是与骨丢失显著相关的因素。单独来看，全身状况对种植体存留率无显著影响。
年龄并非单独禁忌种植体修复治疗的因素。相反，吸烟对牙种植体存留率有显著影响。骨质疏松症、甲状腺功能减退症、糖尿病、高血压和心脏病等全身性疾病，在得到控制时并非禁忌因素。
本研究对于评估老年患者种植体植入后即刻及长期的种植体周围骨丢失情况具有重要意义。因此，可以证实年龄并非该手术的限制因素。得到控制的全身性疾病并非种植体植入的禁忌证，但吸烟是影响种植体存留的一个因素。
